If you are getting 220 to 240 degrees F after flight, I strongly suspect that you have cooling issues / are running too lean. I was told that anything above 220 degrees F is overheating.
I'm not an expert, just passing on what I've been told.
I had what we believe was overheating issues on one of my 150s and better cooling, getting temps down to 210 F max has greatly improved its running, though I also experience that a 3/4 to 7/8 throttle position sometimes gives a better run.

I did more tests with the moki.
The low needle was open to 1 1/2 and high had to be close a litle to 1 5/8 more or less.
the engine is with more or less 4500 with the Xoar 32x18
The temperature was the same.. after landing 220/ 240oF
I did 4 flight and the engine is perfect.. but my point..
The strange think.. i can't see the carb, so i set up the servo until reach the max point with ATV 86%. But this RPM i get with 3 clicks dow in the trotle. So i dow the ATV to 66%. With full power the RPM drop 300 rpm.
i will need a mirror to check if the carb is full open but i never see a gas carb doing that.. what do you think? another idea is that the engine can't have all the fuel that need to full open carb so in this point is stronger than full open..
